Thank you for the reply. Yes rearranging the pins on the big white plug will be the best option - but even taking the original (now useless) one apart I just can't see how to remove and replace those pins. It can't be by pulling out the wires from the rear, otherwise installing the plug would push them out the back. And there's no way to "push" them out the front - there's no way to pull them out in that direction. I see very tiny rectangular holes adjacent to each pin-hole and tried pushing a needle into some of them to see if that released the pins. Even cutting off the surface clip leaves me no wiser, so what's the trick?
